To all whom it may concern: j

Be it known that l, MAUnIoE L. Yusrnn, a citizen of the United States,residing at Rochester, in the cbunty of Fulton and State of Indiana,have invented certain new and useful Improvements in AutomobileCombination-Locks; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figuresof-reierencc marked thereon, which form a part of this specification.

My invention relates to the class of looks but more particularly to adevice for locking the steering column of an automobile or the like insuch manner that the steering column cannot be operated while the deviceis in a locked position, thus clliectually preventing further use oremployment of the machine until the device has been unlocked.

A further object of my invention is to provide a device for locking thesteering column of automobiles or the like which is particularly simplein its construction, cheap and easy to manufacture, strong, 'durable andeflicient.

Nith these objects in view my invention consists in the novelconstruction of the lock and in the novel construction employed forattaching the same to the steering colimm of an automobile.

My invention also consists in certain other novel features ofconstruction and in combination of parts, all of which will be firstfully described and afterward specifically pointed out in the appendedclaims.

Referring to the accompanying drawings: Figure 1 is aperspective view ofthe steering column of an automobile illustrating my de vice inoperative position thereon. Fig. 2 is a transverse sectional view takenthrough the steering column showing the lock in plan. Fig. 3 is avertical sectional view taken through the steering column and through.

the lock, said view being taken on line 33 of Fig. 4. Fig. 4 is atransverse sectional view through the steering column. and lock. Fig. 5is a bottom plan of the lock cap. Fig. 6 is a transverse sectional viewthrough the steerin column showing the dial cover over the dia andillustrating the device unlocked.

tumbler, and Fig. 9 is a plan of the washer.

Like numerals of reference indicate the same parts throughout theseveral figures in which:

1 indicates the steering column of an auto mobile which comprises, theinner tube or column- 2 and the outer tube or column 3, it being usualin the construction of steering columns of automobiles to arrange theouter column 3 stationary and have the inner column 2 rotate within theouter cohnnn 3, said inner column 2 being attached to a steering wheel 4or other analogous device.

5 indicates the locking device which coniprises the permutation lock 6and the con necting arrangement 7 for securing the lock 6 to thesteering column 1. 1

Referring now to Figs. 2, 3 and 4 it will be seen that the lock 6comprises a casing 7 and a cap 8, said cap, as shown in Fig. 3, is provided with a recess 9 within which is accommodated a pointer 10, saidpointer 10 being arranged directly above the dial 11 which is formed onthe cap 8. A central post 12 formed on said pointer 10 enters the bodyof the lock 6 and carries thereon a notched or toothed disk 13 (Fig. 5).As will appear from Fig. 3 a tube 14 extending upwardly from the bottomof the casing 7 receives the cent a-l post 12, and on said sleeve 14 aremounted the upper toothed tumbler 15 and the lower tumbler 16, a washer17 being interposed between said two tumblers, said washer 17 (Fig. 9)being provided with a projection 18 which enters a slot 19 in the tube14, thus preventing said washer 17 from rotating on the tube 14. It willalso be seen from Fig. 3 that a small spiral spring 20 is provided underthe lower tumbler 16, said spring normally holding the said tumblers ina proper relative position. Formed on the upper toothed tumbler 15 asclearly shown in *igs. 3 and 4 is a lug or projection 21, said lug orprojection entering one of the notches in the notched disk 13 on thecentral post 12; While said toothed tumbler 15 is also provided witha'smaller lug or-projection 22 formed on the bottom face of saidtumbler, said lug pr projection 22 being arranged in the path of asimilar lug or projection 23 formed on the upper face of the lowertumbler 16 as cleailg shown in Fig. 3. :Al'- ranged between .t e uppertoothed tumbler locked. Fig. 8 is a plan view of the lower o and'the cap8 is a slide 24 (Fig. 4), said slide 24 comprising a ush rod 25 and alooking bolt 26, said slide iavinga V-shaped dog 27 formed thereon, saidV-shaped dog 27 casing is normally in engagement with the V-shaped dog27, said spring holding the dog 27 in engagement with the toothedperiphery 28 of the tumbler 15.

Referring now to the means for securing the lock to the steering columnit will be seen that I provide a base piece 30 (Fig. 4) and secure sameto the lock by means of two small screws 31, said screws entering theflange 32 of the cap and passing into the flange or wall 33 of thecasing 7, thus securely locking the cap 8 in position on the casing 7 insuch manner that the cap cannot be removed while the device isin'position on the steering column of an automobile. Connected to saidbase piece 30 by means of the screws 31 is a flexible metal strap 34,which comprises the portion 34' and the portion 38, the portion 34partially surrounding the steering column and passing from the point 35to the point 36.

Referring now to Figs. 2, 6 and 7 it will be seen that a slideconnection 37 is provided between the strap portion 34 and the strapportion 38, which strap portion 38 passes around the steering column andunder the strap portion 34, as clearly shown in Fig. 4, two screws 39and '40 being provided for securing the said strap portions 34 and 38'rigidly in position on the outer tube or column 3 of the steeringcolumn 1.

Referring now to Figs. 3 and 4 it will be seen that a perforation 41 isprovided in the outer tube or column 3 and the inner tube ,or column 2in such manner that the locking bolt 26 enters the said perforationsecurely locking the device or columns 2 and 3 against relativemovement. It will also appear from Figs. 4 and 7 that the straps 34 and38 are erforated at 50 and 51 in. order to allow the ocking bolt 26 topass th erethrough and into the steering column 1.

Referring now to Figs. 4 and 8 it will be seen that the-toothed tumbler15 is provided with a notch or recess 42 in the periphery of saidtumbler, whilethe lowertumbler 16 1 (Fig. 8) is provided with a similarnotch or recess 43.

Having thus fully described the several arts of my invention itsoperation is as folows: After the perforation 41 has been made 'in thesteering column of the automobile the device is secured to the column inthe following manner: The lock is manipulated in the'manner as will bepresently described in order to have the locking bolt 26 in an unlockedposition as shown in Fig. 6. The strap portions 34 and 38 arethen-passed around the steering column in the manner as illustrated inFig. 6, and the screws 39 and.40 applied thereto in order 'to securelyhold the said strap portions 34 and 38 in position shown in Fig. 2. Whenthe straps are in this position the lock is manipulated in order toallow the locking bolt 26 to pass through the said strap ortions- 34 and38 and into the steering co umn 1 as shown in Fig. 7. When the lockingbolt 26 is in this position the strap portions 34 .and 38 can not beremoved. from the steering column as long as the locking bolt 26 is inposition shown in Fig.7. In order to operate the lock the pivoted cover44 -is swung into position shown in Fig. 2 so that the pointer 10 isaccessible. Said pointer is then turned, which operation rotates thetoothed tumbler 15.

15 passes under the 'V--shaped dog 27 a clicking sound is given out insuch manner that the extent of movement of the pointer 10 can bedetermined without looking at the dial 11 which also allows the deviceto be operated" in dark, for the reason that the .number of clicks whenonce known can be lower tumbler 16 is brought directly in front of theV-shaped dog 27. movement of the pointer 10 in order to bring thetumbler 16 into this position is of course known to the operator of thelock.

As soon as the tumbler 16 assumes this posi tion the pointer 10 isrotated in the opposite direction, which rotation carries the toothedtumbler 15 until the notch or recess 42 therein lies directly in frontof the V-shaped dog 27 and directly above the notch or recess 43 in thelower tumbler 16. As soon as As the peri hery of said tumbler Theextent. of 1 the toothed tumbler 15 assumes this position the leafspring 29 acting on the V- shaped dog 27 carries said dog within therecesses 42 and 43 in the tumblers 15 and 16 carrying the locking bolt26 within the easing as shown in Fig. 6, thus unlocking the steeringcolumn; In order to again lock the steering column the push rod 25 isforced into position shown in Fig. 4 and the pointer 10 given a turn.This immediately carries the notch 42 in the toothed tumbler 15 out ofline with the V-shaped dog 27 and throws the periphery 28 of the toothedtumbler15 into engagement with the V-shaped dog 27,

thus securely maintaining the locking bolt 26 in a locked position andwithin the steermg column as clearlyshown in Fig. 4.

Having thus fully described my invention what I .c aimas new and desireto secure by Letters Patent of the United States, is: 1. A device forlocking the steering column of an automobile or the like comprising alock, a strap to which said lock is secured, a locking bolt adapted tobe assed into the steering column, said strap eing provided withperforations through which said locking-bolt is adapted to pass, thewhole arranged in such manner that the said strap is locked around thesteering column by the said locking bolt.

2. A device for locking the steering column of an automobile or the likecomprising a permutation look, a strap to which said lock is secured,-said strap encompassing the steering column, a locking bolt in saidlock adapted to pass into the steering column to lock the same, each endof said strap being provided with means for receiving said looking boltto lock said strap on the steering co umn.

I In testimony whereof, I affix my signature, in presence of twowitnesses.
